I have an automatic cleaner* and it has recently been having trouble with the hose getting tangled/wrapped around the cleaner. It came with the house which we've had for 6 years and has worked well most of that time, so I don't think it's an issue of hose length. It seems to me that the floats aren't floating as much as the should because the ones in the middle seem content to stay submerged a few feet down even if there's slack. Also, I'm not sure the swivels swiveling very well. They feel like they have grit in them. Would it make sense to replace the hose? Is there a way to lubricate/clean the swivels?
* I think it's a Letro Legend - it works with a booster pump and looks kind like this: http://www.bestbuypoolsupply.com/legend.html with different colors (it might be Leslie's branded).
